ABtUS AVA-DV19 is a 1 in 9out DVI-D DA. It is good for connecting up to 9 display panels/monitors or more with the loop out. Hence, there is an EDID that will auto-seek continuously for the maximum resolution of the display/monitor, that is connected to this "Loop out" or port number 9. This sets the rest of the out ports resolution based on maximum one.

In situation where two or more displays are connected, users should always connect the lowest resolution display to output port number 9 first. This is to prevent a higher resolution output whereby there will be no image for the lower resolution display in the event that all displays are NOT of the same resolution.
